Become a "writer for hire" and start with small projects. Get with an agency that lets you get paid for helping people with articles, blogs, website content, proofreading editing...all parts of developing your craft. Divide your time between this work and your own work. As you start getting paid, you will feel validates, and better about your craft. It's hard to write a novel or other big work and have no idea if it will ever go anywhere. This has made a huge difference to my writing and now I write professionally every day!!
